Such techniques are aimed to dramatically reduce the time required to solve a problem. This paper examined the Productivity Potential Map (PPM) technique as a heuristic approach tool in assisting the reservoir engineer to choose optimum well locations for field development planning. Eleven well locations were selected using PPM technique and compared with the same number of wells located using conventional STOIIP based methodology.The exercise used information from six vertical wells in Field A, Otter Sandstone Formation (Sherwood Group). It is a discontinuous fluvial system with highly variable permeability patterns which poses a significant challenge for selecting well targets.A comparison of simulated flow performance showed that well locations selected using PPM technique exhibied consistently better performance and minimum variance. STOIIP and PPM techniques resulted in two totally different templates for the selection of well locations. PPM technique was coherent with the expected geological trend of the area than the trend showed by the STOIIP technique.The exercise showed that the PPM technique is a valuable method in delineating reservoir regions with favourable production potential for well placement, especially in complex sedimentary environments.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
